While it is generally assumed that particulate organic matter (POM)
and mineral associated organic matter (MAOM) have distinct
biogeochemical characteristics, it remains unresolved where and why
POM and MAOM differ in their composition and relationships to total
SOM decomposition among heterogenous soils. To address these
questions, we analyzed elemental, isotopic, and chemical
composition, including diffuse reflectance infrared Fourier
transform (DRIFT) spectra, of POM and MAOM in 156 soil samples
collected from 20 National Ecological Observatory Network (NEON)
sites spanning diverse ecosystems (tundra to tropics) across North
America in 2019. We used a classic size separation method for POM
(53–2000 µm) and MAOM (< 53 µm) following chemical dispersion.
